UNITED STATES GEORGE MCLEAN, OF TEXIGO, NEW MEXICO.

CATTLE GUARD.

Application led May '7, 1923.

To all whom t may concern.'

Be it known that I, GEORGE McLnAN, a citizen of the United States of America, and resident of rllexico, in the county of Curry and State of New Mexico, .have invented certain new and useful Improvements in Cattle Guards, of which the :following is a specification.

This invention relates to highways construction, and has special reference to a cattle guard to preventpcattle from passing beyond certain definite points on the highway.

It is well known that automobile roads frequently go through pastures and farms and intersect fence lines. At these fence lines, it is common to provide a gate, and the principal object of the present invention is to provide an improved form of highway cattle guard especially adapted to be placed at the intersection of fence lines and highways so that gates at such places will be unnecessary.

TWith the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

ln the accompanying` drawings like characters of reference indicate like parts in the several views, and:

Fig. 1 is a plan view of such a cattle guard, the highway and fence being indicated in dotted lines.

Fig. 2 is a section on the line 2 2 of Fig. 1.

l'n the drawings illustrating this invention, there is disclosed an ordinary highway H in plan., which intersects a line of fencing F. Between the ends of the fencings on either side of the highway, there is provided a suitable pit or excavation 10, ycement walls 11 beine preferably employed to retain the dirt in proper position, and prevent it falling into the pit.

Secured to the top of these walls 11 are transverse plates' 12, which are preferably in the form of fiat metal bars, and which are held on the walls by bolts 13. On top of these plates rests the guard proper, which consists of a series of longitudinally extending angle irons 14;, each having one leg Serial No. 637,337'.

vertical, and its other leg extending horizontally from the upper end of the vertical leg. These vertical legs rest on the bars 12, while to the horizontal legs are riveted end frame members 15, to which in turn are bolted side frame members 16. Between the side frame members extend iiat guard plates or bars 17, which have their ends riveted to the side frame members, and which rest freely on the horizontal flanges of the angle irons 111. Extending through the end frame members 15, and the supporting plates 12, are held the down bolts 18.

The spacing of the members 17 are such that an automobile or the like, may readily run along the road and across these members without undue injury or disturbance, while at the same time cattle, noting these spaces, will avoid crossing the guard for fear of ruiming into the pit.

Moreover, by reason of the bolts 18, the pit may be cleaned out whenever desired, it being simply necessary to loosen these bolts and lift olf the top or guard frame proper.

There has thus been provided a simple and ellicient device of the kind ldescribed and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. 1t is not, therefore, desired to coniine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

In highway construction, a pit, supporting bars extending across the pit and adapted to be secured in place, a grate supporting structure comprising supporting elements extending across the supporting bars and resting thereon, and anchoring plates at the ends of the supporting elements secured thereto, in combination with a grid comprising end plates having their ends supported on and remotely secure-d to the anchoring plates, and grid bars having their ends attached to the end plates and adapted to cover the pit when in place and to be removed when access to the pit is desired, substantially as described.
